Geologists at the Yellowstone National Park have announced that a third eruption was recorded at a geyser site which rests on top of the masssive active volcano.

The US National Park Service revealed that a park visitor first spotted the rare eruption of Steamboat Geyser on Friday morning.

The “unusual” amount of eruptions at the site, the third over a six-week period, set off fears of a volcanic blast in the Yellowstone National Park.

However, geologists at the park have been quick to clarify that the seismic activity and eruptions are not yet indicative of a more destructive volcanic eruption brewing beneath Wyoming.

Steamboat Geyser previously erupted on March 15 and April 19, after lying dormant for three years.

The geyser in Wyoming can shoot water as high as 300 feet (91 meters) into the air, making it the second most powerful geyser in recorded history.

Scientists have insisted there is no reason to suspect that the increased frequency of eruptions at Steamboat is an indication the Yellowstone caldera—a massive volcanic crater beneath the gesyer – is about to erupt.

Michael Poland, the scientist in charge for the observatory, said: “There is nothing to indicate that any sort of volcanic eruption is imminent.”

The last time the Steamboat Geyser erupted three times in a year was in 2003, according to the U.S. Geological Survey’s Yellowstone Volcano Observatory.
